Selenium Grid is a key component of the Selenium suite that enables distributed test execution across multiple machines and environments. It uses a smart server to route test commands from the client to remote browser instances, allowing for parallel testing across various operating systems and browser configurations. This client-server model significantly speeds up test cycles and improves coverage.
